Title: Production of pectinic acid lyase by use 0f alkaliphilic bacillus bacterium
Inventor: YOSHIHARA KAZUTOSHI
IPC: C12N9/88
Filed: 1979-11-09
Abstract: PURPOSE: A specific alkaliphlic Bacillus bacterium is cultured in an alkaline medium to produce pectinic acid lyase with economic advantage almost without contamination by other bacteria even when the Bacillus bacterium is cultured in an open system.  
     CONSTITUTION: Bacillus firmus GIR277 mold (FERN-5208) is aerobically cultured in an alkaline medium that contains sodium carbonate or the like and is kept to 8.0W10 in pH at 20W40°C for 2W4 days. When the accumulation of pectinic acid lyase attains the maximum, the culture mixture is extracted or filtered, when necessary purified by salting, precipitation with solvents to give pectinic acid lyase in high yield. Since the culture medium is alkaline, other bacteria scarcely grow, therefore, the operations for keeping the medium bacteria-free can be eliminated with advatage. As a carbon source for the culture medium, can be used a powder or pieces of bast fibers such as mitsumata or kozo (for Japanese paper).

Title: Control of direct current motor
Inventor: TAKAHASHI KUNIO
IPC: H02P7/29
Filed: 1978-11-27
Abstract: PURPOSE: To obtain the direct current variable voltage with the reduced wave form distortion by connecting the second rectifier circuit, in which a switching element controlled intermittently by high frequency is connected to the direct current output, to the alternate current input of the rectifier circuit for applying the direct current on the direct current motor.  
     CONSTITUTION: An alternate current source 1, the first rectifier circuit 32, a direct current motor 33, the second rectifier circuit 35, and a switching transistor 37 controlled intermittently by high frequency through a voltage control unit 36 are connected in series. To the first rectifier circuit 32 connected is a smoothing circuit consisting of a condenser 38 and a reactor 39. By so doing, the switching transistor 37 is controlled intermittently by high frequency, so the alternate current voltage supplied to the first rectifier circuit 32 via the second rectifier circuit 35 is interrupted by high frequency. Thus, although the direct current voltage obtained from the first rectifier circuit 32 includes the high frequency component, its wave form distortion is reduced to low level.

IPC: H04L29/06
Filed: 1990-06-06
Abstract: PURPOSE:To reduce the circuit scale of the advanced start priority circuit and to prevent delay time from an input to an output from being increased by generating the output of a specified code when the input of the specified code is applied, holding the state of the output and executing reset according to the state of outputting the specified code for any other data holding means. CONSTITUTION:When a code '1' is applied as a reset signal XRESET and an input data DI1, is turned to the code '1', the '1' is outputted to an output terminal Q of a flip-flop 101 with the rising of a clock signal CK, the output data DI1 is turned to the code '1' and held, and a code '0' is outputted to an inverted output terminal XQ. By outputting the code '0' to the inverted output XR of the flip-flop 101, the output of a gate 202 is turned to the code '0' and therefore, a flip-flop 102, is turned to a reset state. Thus, even when the code '1' is applied to an input data DI2, of the flip-flop 102, the flip-flop 102, cannot be set.

Title: Safety device for elevator
Inventor: KOBAYASHI HIROSHI
IPC: B66B5/06
Filed: 1989-06-08
Abstract: PURPOSE:To prevent passengers from secondary accidents so as to heighten safety by constructing the title device in such a way as to inform the passengers of abnormality through an alarm by the detecting action of a first overspeed detector and operate the brake of an elevator driving part by the detecting action of a second overspeed detector. CONSTITUTION:When the speed of a cage exceeds the rated speed due to the generation of abnormality to an elevator, a first overspeed detector 5A is kicked by a pendulum 4 to be placed in detecting action immediately before the sudden stopping action of the cage, as well as an alarm rumbles to inform passengers in the cage of the abnormality. The passengers thus become aware of the abnormality of the elevator by the alarm and prepare themselves instinctively for self-defense. When the cage speed is further increased and reaches the 1.3 times higher than the rated speed, a second overspeed detector 5B is kicked by the pendulum 4 to be placed in detecting action so as to cut off a power circuit to a winding machine motor as well as actuate the electromagnetic brake of the winding machine to stop the cage suddenly. The passengers receive large physical gravity G, but since they are prepared instinctively for self-defense, shock is less and such secondary accident as being injured can be prevented.

Title: Automatic point soldering mechanism
Inventor: KOMATSUBARA YASUYUKI
IPC: H05K3/34
Filed: 1986-06-25
Abstract: PURPOSE:To always feed a string solder at a fixed position for a soldering iron tip even if the upper and lower positions of a soldering substrate vary, by performing the positioning of a solder supporting part by the stopper in the space with a soldering iron tip supporting part and fixing the relative position of the both supporting parts. CONSTITUTION:With the actuation of an air cylinder 3 a soldering iron tip and solder supporting parts 11, 10 are descended symmetrically by being pushed down with springs 18, 19 and a string solder 2 is pinched between the soldering iron tip 1 and a pad lead 4. The soldering iron tip 1 is lifted by a spring 5 just before its abutting the lead 4 and finally positioned by the stopper 6, which is adjusted so that the soldering iron tip 1 and solder 2 may become an optimum positional relation in advance and the positional relation of the both is always made constant. The supporting parts 11, 10 are pressed via springs 18, 19 by the cylinder 3 and when the soldering iron tip 1 is abutted to a substrate 14 before the stroke end of the cylinder 3, the springs 18, 19 are contracted and the soldering iron tip stops at that time. The soldering iron tip is therefore following up the substrate 14 at all times even if the soldering position moves up and down by the deflection of the substrate 14, etc. and the solder 2 follows the soldering iron tip as well, so it becomes feedable to the constant position always.

Title: Manufacture of multidimensional quantum well structure
Inventor: TAKANO SHINJI
IPC: H01L29/201
Filed: 1988-06-14
Abstract: PURPOSE:To realize multidimensional quantum well structure easily with good reproducibility by forming a semiconductor layer by vapor growth which is enough thin to make a quantum effect on fine irregularities formed on a semiconductor substrate and by changing a part of a composition of the semiconductor layer at recesses and protrusions of the irregularities. CONSTITUTION:When an InGaAsP guide layer 20 and an active layer of an InGaAs/ InGaAsP quantum well structure 30 are made grow on an InP substrate 10 through vapor growth, a composition of a growing part on a recess of diffraction grating changes and the active layer is divided. This is mainly because atoms of III group collect to a recess area, and a width of a part whose composition changes depends on a depth of a recess, a thickness of a guide layer, etc. Therefore, it is possible to control a size of an effective region as an active layer by adjusting a grating depth and guide layer thickness properly. A two dimensional quantum well (quantum fine line) structure 33 can be obtained by forming an active layer of a quantum well structure 30. Moreover, three dimensional quantum well (quantum box) structure can be realized by forming dotted irregularities on a substrate by applying interference exposure method twice and by forming a quantum well active layer on the substrate.
